Minecraft version - 1.18.2
Mod loader - Forge 40.2.0
Mod version - 1.5.5
I am using the latest version available - Yes

Describe the bug
I created my server with the forge server installer.
As soon as I start my own server (which I created to play with friends), it crashes. In the server mod file, I only put the mods: Better Combat, Cloth config, Player animation lib.
I don't really know if I did something wrong when I created the server or if it's the mod that makes it crash.
I put the log message down below :

I can also say that with some other mods, like Terralith, the server works.

Hello!
These error logs don't show any specific reference to Better Combat, nor can I reproduce the error.
I recommend going through the troubleshooting guide on our Discord server.
Closing this issue due to lack of actionable data.
